Bluetooth headphones are ideal for use on the go. They do not have a wire that tangles in a pocket into a Gordian knot. These headphones receive sound from:
- Smartphones.
- Smart TVs.
- Tablets.
- Computers.
- Smartwatches.
A wireless earphone needs to be charged, but if the charge runs out, you can always get the cord and use it like a regular headset. And how to choose wireless headphones with good sound, we will tell below.
Bluetooth version
The newer the version, the cleaner and better the quality of the received signal. Also in the new version, the headphones spend less energy. Version 5 is now available. But models with it are much more expensive. In addition, the same version must be supported by the gadget from which the signal will go. If the headphones are version 5, and the phone is only version 3, the sound quality will be the same as the latest.
You should not buy headphones below Bluetooth version 3 – the sound is not very good there.
Radius actions
In most cases, wireless ear phones will be within a meter of your phone or PC. But if you like to move around the apartment or office, then the distance will increase. In this case, you need a model with a radius of 10-20 m.
Declaring a long range, manufacturers are silent that a good signal will only be in a clear space. Walls, partitions significantly reduce the sound quality and reduce the radius by almost half.
Form factor
Wireless headphones, like conventional models, can be internal and external. The former is miniature in size, due to which they fit compactly in the ears. In-ear headphones are ideal for those who like to move around the city with music.
External on-ear headphones have a hoop and are superimposed over the ears. They are bulkier and heavier. But they do not rub the skin, hold the charge longer and have a cleaner sound.
Number of channels.
If more than one Bluetooth headphone is used in the room, then each of them must have several channels. Otherwise, the headphones will begin to receive signals from different smartphones (PCs), and you will get “audio porridge”. Select a model that supports multi-channel transmission.
Headphone sensitivity
It depends on the sound volume. A sensitivity of 95dB or more will suffice.
Resistance (impedance)
For in-ear headphones, the optimal resistance is 16-32 ohms. If the headset will be used in tandem with a smartphone or tablet, then 16 ohms will be more than enough.
Over-ear headphones need an impedance of 2000-2200 ohms.
NFC technologies
With its help, the headphones will pick up a Bluetooth signal as soon as they are near the phone. Pairing will happen automatically.
The presence of a microphone
In order not only to listen to music, but also to talk on the phone or chat, you need headphones with a microphone. The latter can be built-in or external.
Noise suppression
If you don’t want to hear outside noise, consider noise canceling headphones. These can be vacuum headphones and external models of a closed type.
Headphones can independently cancel noise when necessary. But with Active Noise Canceling technology, the headset consumes battery much faster.
A2DP support
This profile noticeably improves the sound quality of Bluetooth headphones. If you are a music lover, choose a model with A2DP or regular wired models.
AVRCP profile
It allows you to control devices (phone, music center) at a distance: decrease / increase the volume, rewind, etc. But this profile must also be in the device transmitting sound.
Extra options
When choosing a headset, look at battery life. But the declared indicator will be valid only for a confident signal and not at the highest sound volume.
The choice of color and design of the headband depends only on personal preferences. But the presence of the volume control will be very convenient. No need to take out your phone, look for the right tab or reach for the speaker to adjust the sound.
